Described control circuit 10 is made up of single-chip microcomputer and peripheral circuit thereof.

On the pneumatic tube 5 between described many gas source nozzles 3 and the electronic control pressure reducing valve 2, go back and be connected to tracheae 8 into many sources of the gas hypoxia protection or flame-out protection device 7 air feed.

Automatically controlled Flow valve 9 is installed on the pneumatic tube 5 between described electronic control pressure reducing valve 2 and the many gas source nozzles 3, and the control end of automatically controlled Flow valve 9 links to each other with the output terminal of control circuit 10.

The utlity model has following advantage:

The utility model can make the performance of many sources of the gas gas combustion apparatus be further improved, and it is more convenient that the user is used.

Control system of the present utility model is simple in structure, and is safe and reliable, easily manufactured, and control circuit wherein can adopt prior art to be realized.Having under the selectable situation of multiple combustion gas, also can be designed to automatically to select according to parameters such as ambient temperature, working medium temperature the air supply system of corresponding combustion gas kind by control circuit being carried out suitable expansion, so it is having good expansivity.
